그럼 혹시 예외 타입으로 검증하려면 어떤 방식으로 진행해야 하나요?

assertThrows(IllegalStateException.class, () -> {
    memberService.join(member2);
});

감사합니다!

OMG

검증 구문이 잘못되었네요.

테스트 목적에 맞게 작성하려면 다음과 같이 작성하는게 맞을 것 같습니다.

assertThatThrownBy(() -> memberService.join(member2)).hasMessage("a"); 
혹은 hasMessageContaining()로 검증

아래와 같이 "a" 문자열을 message로 넘겨서 테스트를 진행해 보았지만,

같은 에러 메시지가 출력됩니다.

MemberService.java

private void validateDuplicateMember(Member member) {
    List<Member> findMembers = memberRepository.findByName(member.getName());
    if(!findMembers.isEmpty()){
        throw new IllegalStateException("a");
    }
}

MemberServiceTest.java

@Test
public void 중복_회원_예외() throws Exception {
    //given
    Member member1 = new Member();
    member1.setName("kim");

    Member member2 = new Member();
    member2.setName("kim");

    //when
    memberService.join(member1);

    //then
    assertThatThrownBy(() -> memberService.join(member2))
            .isEqualTo(new IllegalStateException("a"));

}
